论述了湖南省桑植县氵娄水河地区的柏木生长年轮特点。根据柏木年轮资料分析得知 ,氵娄水河近百年间曾有过 1 9次冷期阶段和 1 9次暖期阶段 ,文中表 2显示了近百年氵娄水河地区气候冷、暖阶段 2～ 3年循环变化的周期规律 ;通过年轮宽度指数与气候因子的相关性分析 ,为氵娄水河地区柏木生长的历史气候变化及环境变化提供了基础研究资料。 The characteristics of growth cycle of cypress wood in Lou Lou River in Sangzhi County, Hunan Province are discussed. According to the analysis of the Kashiwagi ring data, it has been learned that there are 19 cool-down periods and 19 warm-down periods in the Loushui River in recent 100 years. Table 2 shows the cold and warm phases of the Loushuihe area in the past century The cycle regularity of 2 ~ 3 years was analyzed. Based on the analysis of the correlation between the annual ring width index and climatic factors, the basic research data were provided for the historical climate change and environmental changes of the cypress trees in the Lou water area.
